To all whom it may concern."

Be it known that I, GUsTAvE A. WINEMAN, a citizen of the United States of America,

residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Cash- Rcgisters, of which the following is a specification, reference being lhad therein to the accompanying drawings.

This invention relates to cash registers, and more especially to the registering mechanism proper.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

The invention is herein illustrated in connection with a cash register which incorporates the other featuresof cash till locking and releasemeans or till controlling mechanism, means for returning the registering device to initial position or resetting mechanism, together with interlocking .members all of any suitable type, but preferably as shown in my Patentv No. 952,554, issued March 22,1910 for cash registers, of which this is a divisional application.

In the drawings, Figure l is a view in transverse section of a cash register provided with registering' mechanism embodying features of the invention. Fig. 2 is a plan view, with parts of an exterior casing in section and'broken away, showing the general arrangement of the registering mechanism together with parts of resetting means. Fig. 3 is a View in detail, enlarged and partially broken away, of the resetting mechanism. Fig. 4 is a view in detail of a pair of registering wheels with spacing collars and'star spring in position for Aassembling, with the position of a universal stop bar indicated. Fig. 5 is a view in detail showing the register kwheels and the arrangement of the numerals thereon in reference to a view slot of an inner casing cover.

Referring to the drawings, l indicates an exterior casing of suitable design, having a cash drawer or till 2 yin its base, over which the registering mechanism is secured, and

end frames 3 being provided for carrying the w orking parts.

As herein illustrated, the registering mechanism has a main shaft al journaled at each cnd in the frame 3, and provided with a key seat or groove a2 extending throughout its length. A series of pairs of ratchet Wheels are rotatably secured in regular spaced relation on the shaft. In a preferred form of construction the master wheel of each `pair is a thin disk a3 having a flange ring at on one face thereof and regular ratchet teeth a5 in its periphery, one of which is more deeply cut than the others to form a master tooth a6. The liange ring at hason its periphery a series of numerals corresponding to the teeth in number, and a radial stop a7 which, for convenience in arrangement of coacting mechanism, is several spaces or teeth ahead of the master tooth a, The second or follower Wheel a8 is of like construction, but of less diameter, its ratchet teeth a9 coming in register one by one with the master tooth of, so as to be engaged simultaneously therewith by any operating pawl. The wheels of each pair are set back to back against a stop or spacing collar al@ secured to the shaft a?, a washer all being placed between the wheels with a star or spider ,spring a rotatable on the shaft in compression between the outer wheel and the spacing collar am of the adjacent pair. Other suitably disposed forms of friction spring members may be used. The outer margins of the adjacent flange rings at of adjoining wheels are separated by circular division plates als, of slightly greater diameter than the rings, which are secured on the .spacing collars al", a longitudinal key-seat or groove a in the collar being engaged by a lug or feather pin L15 on the plate. A locking ratchet wheel al with teeth opposed to the register wheel teeth is keyed or otherwise secured to the sha-ft a1, with a detent or latch pawl f engaging it and preventing the rotating of the register wheels from accidentally turning the shaft. A bank of operating lever keys b1 are pivoted below the registering wheels on a rod b2 parallel to the shaft al secured to the end frames ll. The outer arms of the keys play in guide slots 3 in the outer casing and finger buttons b4 with numerals thereon are secured in the upturned extremities with segmental shields h5 preferably integral with the levers ust behind the guide slots. The inner arms of the keys oscillate in guidegslots 5 in an upright plate l G connecting the end plates. A pawl b is pivoted on the inner arm of-each key and is held by a suitably disposed spring 127 in engagement with the master ratchet wheel a3 of the pair of registering wheels in whose plane of rotation the key swings. The pawl may be conveniently stamped out of sheet metal as herein illustrated, and iven a half twist to provide a bearing endg sufficiently wide to engage both master and follower wheel teeth when engaging the master tooth a". V

The numerals on the wheel flanges are disposed transversely as indicated and are soarranged that when the wheels are in initial position, the zeros appear under a view slot g1 of a plate g? acting as an inner cover over the wheels; thus by opening the outer casing at any time after the wheels are set, a column of figures is presented across the machine in such position that they may be readily tered sum without any trouble of trans ring the items to paper. .t

The numerals on the lever finger plates give the value or amount registered by each key in the usual manner while each follower wheel of a pair is a totaler of the numerals on the master wheel ring, the series on the latter being multiples of the engaging lever button numeral as usual in this class of machines. i

A universal stop plate f1 is secured atits rear edge to a pivot bar f* so journaled in the end frames parallel to the register wheel shaft al that a downturned front'flange fs on the plate overhangs the bank of register wheels. A suitable spring f holds it clear of the wheels normally but it may be pressed down by a finger lever f underlying an aperture g3 in the inner cover plate g2 so that its flange f?, which has notches 7"" adapted to bridge the register wheel division plates a, is in the paths of the stop pins a" on the wheel rings.

A ratchet wlieelj oppositely disposed to the locking ratchet al is enga ed by a dog f on a yoke fo oscillating on t e shaft a1, its elongated bearing slot n permitting it to be returned over the ratchet teeth, and a handle socket f1 being provided for a removable handle bar f. The latch` pawl f1* reviously described in connection with the ooking ratchet a, is a rock arm of the pivot bar f2 and has a safety trip linger f" which strikes the segment pawl d and moves it back when the stop plate is depressed.

When therocking'of the resetting yoke has brought all the stopl pins against the flange f1, the zeros of t e wheel rin are all alined under the view`slot` g1L of t e inner cover g. Y

One feature is the fact that the registering wheels are not loaded or engaged with the resetting mechanism at all save through the frictional engagement of the main shaft, while the resetter itself is noiseless in action exce t on the return Iof the yoke over the sin e ratchet wheel.

ne especial point of advantage is the added, thus giving the total reg1s! throwing up of the cumulated values of the several wheels in a column that can be added or totaled without transcribing the items', as usually has to be done in machines of this kind. Another feature is the arrangement whereby the division disks are keyed or splined to the shaft i wheels so that they prevent dragging of one wheel by its rotating companion in case dirt or the like drops between them or their rin s become sprung so as to run together.

bviously, changes in the construction may be made without departing from the spirit of the invention, and I do not limit myself -to any particular form or arrangement of arts.

In a cash re ister, a rotatable main shaft, a series of independent register wheels journaled thereon, and resetting mechanism consisting of spacin collars secured on the shaft between the w eels, a spring lmember on the shaft 'in com ression between each collar and adjacent wlieel, means adapted to positively arrestthe wheels in predetermined position when moved into en agement therewith and to lock the shaft w en not in position to enga e the wheels, and means to rotate the sha when it is unlocked.
